Extend both arms in front of you. Make a small circle with the index fingers and thumbs of both hands. Looking through the circle, focus on a distant object. Draw the circle back towards you, still focusing on the object. The eye in line with the circle is the dominant eye. If you are shooting an air rifle, the gun should rest on the same side as your dominant eye.
Breath and relax the body before aiming. Take a deep breath and exhale halfway. Hold your breath halfway exhaled as you aim and squeeze the trigger, then exhale. You can practice this technique without your gun to get used to it.
To adjust your aim left or right from this position, move your feet. To correct aim up or down, raise or lower the gun.
To adjust aim left or right, pivot your body on the left elbow; to correct aim up or down, move your left hand backward or forward, respectively.
Aim by pivoting your body on your right foot and adjusting your left foot for balance.
Aim left or right by pivoting the body from the waist, and up and down by adjusting your left elbow’s position. [1] X Research source
Keep your index finger off the trigger (resting along the side) and hold the gun with both hands. Bring the gun to eye level.
Do not keep your eye too close to the backside of the aim as it may damage your eye.
Exhale fully only after your target is hit. [2] X Research source
